Lamellar Composites Formed by Sputter Deposition; Properties and Potential Application to Turbine Blades

Abstract

This report presents the results of the research done during the second year or Phase II of an investigation of the properties and behavior of lamellar composites formed by sputter deposition. Two approaches have been investigated in parallel in Phases I and II of the contract. Both were expected to result in yield strengths on the order of 1% or more of the modulus of the composite material. The thin-layered approach, with about 50 A thick layers, was expected to derive its strengthening from interface effects between layers and the small thickness of the layers. The compound-forming approach, with about 2000 A thick layers, was expected to derive its strengthening from the bulk properties of the components and their reaction products.
